The best parts of this book were the following:
1) The cut-outs of pills on the front cover.
2) The steamy scenes, a frigid girl turning wild, and a possessive lesbian sort of romance.
3) The simplicity of the color-coded dolls: red to sleep, green to get thin.
4) The wild crazy romp into a loony bin that was a cross between Girl Interrupted, 1984, One Flew Over the Cuckoo's Nest, and Mean Girls on the Magic Mountain.
5) Lots and lots of booze, and the strange idea that champagne will make you fat, but not Scotch.
6) Women who are sort of assertive, and then totally not.
7) Substance abuse and extramarital sex as the only joys in life.

Downsides:
1) Endless decadence and little reason to care for the characters.
2) Not enough sex, and way too much unhappiness.
3) Holy crap, this book is long!
